The Serial Bus Servo Driver Board is a compact, high-performance controller engineered to manage up to 253 ST/SC series bus servos for complex robotic systems. Featuring both USB and UART communication interfaces, it acts as a central bridge between a host controller and the servo network, operating on a 9-12.6V DC power supply. Its core strength lies in not only sending commands but also reading real-time feedback on each servo's angle, load, and voltage. This complete integration of power management and bi-directional control circuitry streamlines the development of advanced robotics, from multi-axis robotic arms to sophisticated legged robots.

High-Capacity Servo Control
This servo driver board unlocks the potential for large-scale robotic projects by supporting the simultaneous control of up to 253 ST/SC series bus servos. This capability allows for the creation of highly articulated and intricate mechanisms, far beyond the limits of traditional PWM servo controllers, making it perfect for systems with a high degree of freedom.
Flexible Dual Communication Interfaces
Equipped with both USB and UART interfaces, the bus servo controller offers exceptional versatility. The USB port provides a straightforward plug-and-play connection to a host computer, ideal for rapid prototyping, debugging, and direct control via software. The UART interface allows for seamless integration with a wide range of microcontrollers and embedded systems, providing a reliable communication link for deployed applications.

Real-Time Data Feedback
A key advantage of this serial bus Servo driver board is its support for bi-directional communication. It can query each servo individually to read back critical operational data, including current angle, operational load, internal voltage, and working mode. This feedback is essential for creating sophisticated, closed-loop control systems where precision, error detection, and dynamic adjustments are required.
Simplified and Stable Power Integration
The serial bus servo driver board features both a DC 5.5x2.1mm socket and a terminal block for power input, accommodating a 9-12.6V supply that matches the operating voltage of the servos. This dual-input design provides flexibility for both prototyping and permanent installations, while the integrated stable control circuitry ensures reliable power delivery for smooth and consistent servo operation.
Advanced Servo Configuration
Beyond simple rotational control, this driver board allows for advanced configuration of connected servos. It provides the functionality to programmatically set unique IDs for each servo on the bus and to switch their operational state between standard servo mode (positional control) and motor mode (continuous rotation), offering greater customization for diverse mechanical designs.
